It's simply a matter of putting all the necessary materials together, and then it's done.

The working principle of energy gems is also very simple.

The sealing stone, which is fused into the magic crystal, will continuously absorb the natural magic power inside the magic crystal, and then release it through the conversion hydrogel that wraps around it.

As for the magnitude of the released power, that depends entirely on the amount of energy required by the carrier.

Fully automatic, that's how convenient it is.

Of course.

The description above states that energy gems can continuously supply magic power.

But in reality, you still need to rest.

It's like a power bank.

When resting, it absorbs and stores the natural magic from the air.

If too much energy is used continuously at once, the magic power inside the energy gem will eventually be depleted.

"Zhang Yuan, give me a hand and stuff this thing into that pile of weapons and armor."

Ouyang Qianjin handed the finished energy gem to Zhang Yuan.

He then slightly raised his chin, indicating what the other person needed to do.

Zhang Yuan blankly took the energy gem, then turned to look at the pile of weapons that was six or seven meters high on the ground.

Below the weapon was the largest wolf skin, measuring three meters by three meters, covered with intricate runes and alchemical magic circles.

Some of these weapons were taken from Ouyang Qianjin's cart, while others were just collected by the skeleton soldiers at the front line.

After all, besides corpses and bone clubs, the corners of the fortress now have the most weapons.

It's no problem to collect as much as you want.

However, time is of the essence now. Even if Ouyang Qianjin had the skeletons throw the weapons on the ground into the defensive circle between battles, and then have one skeleton collect them, that would only be enough to collect so many.

If you give her a little more time, she might be able to build it to a height of ten meters.
